The wick is made of a high grade of cotton or linen. The material is woven (or braided) so that it will burn in one direction and will curl so that its end remains in the candle flame's oxidizing zone for even and intense burning. Often, wire-core wicks are used.
Differentiate among the non-urinary waste management systems. The excretory system is a passive biological system that removes excess and unnecessary materials from the body, so as to help maintain homeostasis and prevent damage. The main organs involved in waste management are the skin, lungs, liver, and kidneys.
It is one (1) of four (4) organ systems that are responsible for excretion. Excretion is simply a process by which the body gets rid of waste materials, such as urine, faeces, excess water and carbon dioxide. The other three organ systems responsible for excretion are the respiratory system, the digestive system and the integumentary system.
